Methods, systems, and compositions for neuronal differentiation of multipotent stromal cells

Abstract

Some embodiments of the invention comprise methods, systems, and compositions to selectively induce, whether in vitro or in vivo, the neuronal differentiation of multipotent stromal cells through the application of microRNAs, including but not limited to miRNA-124, miRNA-137 and / or miRNA-9* expression products of those miRNAs, and molecules and compositions containing functional elements of those miRNAs. Some embodiments of the invention also comprise the therapeutic administration and use of such induced cells to treat mammalian injuries and diseases, including but not limited to, nervous system injuries or diseases that may otherwise result in decreased cell or system function.

Description

TECHNICAL FIELD[0001]Without limitation, certain embodiments of the invention relate to induction and application of cell types for the treatment of mammalian nervous system injuries and diseases.BACKGROUND[0002]Certain nervous system injuries, autoimmune diseases affecting the central or peripheral nervous system, and neurodegenerative diseases are characterized by loss of specific cells, or abnormal functions of existing nerve cells, which cause the patient to present with different neurological signs and symptoms and potentially irreversible loss of neurological functions. As one example only, some patients suffering stroke, spinal cord injury, or other neural injury and degeneration experience loss of functioning cell types, or neurological conditions like Parkinson's disease and Alzheimer's disease which in turn results in loss of or abnormal function of system function. Currently therapeutic options for treating and restoring such cell and system functions are limited. Thus, a...

Benefits of technology

[0003]Without limitation to only those embodiments described herein and without disclaimer, some embodiments of the invention comprise methods, systems, and compositions to selectively induce, whether in vitro or in vivo, the neuronal differentiation of multipotent stromal cells through the application of microRNAs, including but not limited to miRNA-124, miRNA-137 and / or miRNA-9* expression products of those miRNAs, and molecules and compositions containing functional elements of those miRNAs. Some embodiments of the invention also comprise the therapeutic administration and use of such induced cells to treat mammalian injuries and diseases, including but not limited to, nervous system injuries or diseases that may otherwise result in decreased cell or system function.

Problems solved by technology

As one example only, some patients suffering stroke, spinal cord injury, or other neural injury and degeneration experience loss of functioning cell types, or neurological conditions like Parkinson's disease and Alzheimer's disease which in turn results in loss of or abnormal function of system function.

Currently therapeutic options for treating and restoring such cell and system functions are limited.
